1. The Human Visual System in electronics engineering education

Author

Santos, Beatriz Sousa

Subjects
Human Visual System, digital image processing, computer graphics, human computer interaction
Abstract

Understanding the Human Visual System is fundamental in certain areas as Digital Image Processing, Computer Graphics, Visualization and Human Computer Interaction, where methods and systems are designed to produce images meant to be viewed by humans. A brief description of the way such a topic is addressed in several elective courses of the last year of the Electronics Engineering degree offered at Universidade de Aveiro is presented. The commented bibliography is also described., A compreensão do Sistema Visual Humano éfundamental em áreas em que são desenvolvidos métodos esistemas que produzem imagens destinadas a serem usadaspor observadores humanos. Descreve-se brevemente a forma como é ensinado este tópico em disciplinas de opção da Licenciatura em Engenharia Electrónica e deTelecomunicações da Universidade de Aveiro. Apresenta-setambém a bibliografia comentada.

Abstract

Abstract: Polygonal meshes are used in several application areas to model different objects and structures. Depending on the application, mesh models sometimes have to be processed to, for instance, reduce their complexity (mesh simplification). Such operations introduce differences regarding the original mesh, whose evaluation is of paramount importance when choosing the processing methods to be applied for a particular purpose. Although some mesh analysis and comparison tools are described in the literature, little attention has been given to the way mesh features and mesh comparison results can be visualized. Moreover, particular functionalities have to be made available to enable systematic use and proper data analysis and exploration. PolyMeCo—a tool for polygonal mesh analysis and comparison—was designed and developed taking the above objectives into account. It enhances the way users analyze features and compare meshes by providing an integrated environment where various mesh quality measures and several visualization options are available and can be used in a coordinated way, thus leading to greater insight into the visualized data.
